“One of the fun things of our show is the opportunity to tell big stories about how technology is changing our lives, and the planet around us,” PERSON OF INTEREST creator Jonathan Nolan noted. “But now Reese is pretending to be a New York City police officer, [and] his day job pulls him into some more grounded, dark, emotional landscapes. In this case, it’s the story of a murder of a family that Carter began investigating a few years beforehand. It’s a cold case where the main suspect has fled the country. He’s now come back to the country, the Machine has given us his number, and it’s an opportunity for Reese to pick up where Carter left off in trying to solve this mystery. But the episode really is about more than the case; it’s about the mystery of who is Reese? Who is he really?”
